I have been using asp.net Validator controls for quite long. I have come across the unexplored property of Compare Validator which can check input against following types
1) Currency
2) Date
3) Double
4) Integer
5) String
you can use the Validator by setting the following properties
Operator="DataTypeCheck"
Select any of the below types for data type check
Type= Currency
Date
Double
Integer
String
Example:
<asp:CompareValidator ID="CompareValidatorNumber" runat="server" ControlToValidate="txtTelephone" Text="*" Display="Dynamic" ErrorMessage="Please enter numbers only" Operator="DataTypeCheck" Type="String"></asp:CompareValidator>
